Cantilever bracket mounted on a seat

Abstract

A cantilever bracket mounted on two headrest supporting rods of a seat and includes two cantilevers and a post. The cantilever has one end provided with a fixing seat having a through channel through which the corresponding rod can pass, and the other end provided with a pivot seat. The post having one end provided with a supporting portion for supporting or hanging an object, and the other end provided with a first pivot which passes through pivot holes of the two pivot seats and pivotally connects the two cantilevers as a single unit of which the distance between the two fixing seats is adjustable. The cantilever bracket is applicable to seats of various headrest supporting rods with different spacings therebetween and eliminate the need for brackets of different specifications in accordance with the various headrest supporting rod spacings.

What is claimed is: 
     
       1. A cantilever bracket to be mounted on two headrest supporting rods of a seat, comprising:
 two cantilevers, each said cantilever having an end provided with a fixing seat, each said fixing seat being provided with a through channel through which corresponding said rod passes, each said cantilever having an opposite end provided with a first pivot seat, each said first pivot seat being penetrated by a pivot hole, wherein each said fixing seat has an inner wall surface concavely provided with a receiving cavity for receiving a buffer block, the receiving cavities corresponding in position to the through channels respectively, each said fixing seat further having an outer wall surface provided with a through hole, the through holes being in communication with the receiving cavities respectively, thus allowing an end of a first threaded fastener to pass through a corresponding said through hole, be threadedly fastened to the buffer block in a corresponding said receiving cavity, and be pressed tightly against a corresponding said rod either directly or indirectly; 
 a post having an end curved into a supporting portion for supporting or hanging an object, the post having an opposite end provided with a first pivot, first pivot passing through the pivot holes of the two first pivot seats such that the two cantilevers are pivotally connected as a single unit; and 
 an elastic pad having a periphery pressed against a bottom of the first seat of one said cantilever at a position adjacent to the pivot hole of the corresponding first pivot seat, the elastic pad being centrally provided with an aperture through which an end of a second threaded fastener passes so as to be threadedly fastened to the first pivot, thus pressing the periphery of the elastic pad tightly against the bottom of the corresponding first pivot seat.
